Another sample of the same compound of mass 4.14 g yielded 2.60 g of SO 3 as the only sulfur containing …
How to Find Empirical and Molecular Formula Given Mass Percent
WebJul 27, 2024 · Steps. First determine the molar mass of the empirical formula, which is 31.0571 g/mol. Divide 62.11 by 31.0571 and this will give you 2. Next, multiply all the subscripts in CH5N by 2. This gives us C2H10N2. And that’s it! Follow the steps, practice, and you’ll be able to solve these types of problems with no problem. WebMolecular mass of C 2 H 4 = 2 × (M o l e c u l a r m a s s o f C) + 4 × (M o l e c u l a r m a s s o f H) = 2 4 + 4 × 1 u = 2 8 u f1 cota winners
